View Example: How to Set the Initial Dashboard State

This example demonstrates how to manage dashboard state to save and restore selected master filters values, current drill-down levels, and other parameters such as Treemap layers.

When the application starts, the DashboardControl loads the dashboard and the DashboardState object is deserialized and restored using the GetDataFromString method in the DashboardControl.SetInitialDashboardState event handler.

C#

using DevExpress.DashboardCommon;
using System;
using System.Windows;
using System.Xml.Linq;

namespace WpfDashboard_DashboardState
{
    public partial class MainWindow : Window
    {
        public static readonly string PropertyName = "DashboardState";

        public MainWindow()
        {
            InitializeComponent();
        }

        DashboardState GetDataFromString(string customPropertyValue){
            DashboardState dState = new DashboardState();
            if(!string.IsNullOrEmpty(customPropertyValue)) {
                var xmlStateEl = XDocument.Parse(customPropertyValue);
                dState.LoadFromXml(xmlStateEl);
            }
            return dState;
        }

        private void dashboardControl_SetInitialDashboardState(object sender, DevExpress.DashboardWpf.SetInitialDashboardStateWpfEventArgs e){
            var state = GetDataFromString(dashboardControl.Dashboard.CustomProperties.GetValue(PropertyName));
            e.InitialState = state;
        }
     }
}
